What Kind of Critter are You?

I have a tortoise. He is “piercet” – we have drilled a hole in his shell, so he can enjoy the free life in our garden all Summer. I have several times seen different cats sitting and staring in disbelief at him, and I can almost hear them think: “What kind of critter are you?”.

"Are you an animal?"

"You don’t look like one, but you move."
